Police in Duncanville, Texas fatally shot an armed man on Monday morning after he allegedly entered a day camp facility, shot through a glass window, and threatened to “shoot up the place.” Police said the gunman, 42-year-old Brandon Keith Ned, walked into the lobby area of the Duncanville Fieldhouse, a sports venue roughly 10 miles southwest of Dallas, where about 250 children between the ages of 4 and 14 were attending camp. After a short discussion with a staff member, he fired a shot through a glass window. Cops were on scene within two minutes and found the man armed with a handgun in the gymnasium. They “exchanged gunfire” and the man was killed, NBC5 reported. Naomi Rodgers, a camp counselor, told NBC5 she was in a room with about 40 children when another staff member ran in and said, “We have an active shooter right now!” She added, “The shooter actually came to our door ... and he said if we didn’t let him see who he wanted to see he was going to shoot the place up.” According to police, no children were harmed. Court records indicate that Ned was sentenced to two years in jail in 2011 for intoxication manslaughter, but police have not provided any details on a possible motive for Monday’s incident.
